IMPROVEMENT IN'PLANE-IRONS.

Specification forming part of Letters Patent No. 165,291, dated Ju y 6,1875; application filed May 15, 1875.

' To all whom it may concern giving the plane more iron, and thereby theannoying loss of time and the difficulty connected with thescrew-locking be avoided.

The invention consists of a slotted planeiron to which the cap-piece islocked by an eccentric lever pivoted to a post of the same.

In the drawing, A represents the plane-iron and B, the cap-piece, whichis adjusted by a post, 0, sliding in the longitudinal center slot D ofthe planeiron to the required position for use. The post 0 is secured,by a countersunk base-plate, to the cap-piece. A locking-lever, E, witheccentric E, pivoted to post 0, swings to either side of the same, andlocks, by the eccentricity of its sides, the cap to the iron whencarried down on the latter, while admitting the ready setting when it isin a raised position. The plane-iron is fitted tightly in the stock by awedge-key in the usual manner, the countersunk base-plate of the post ofthe cap-piece requiring no grooving oi the key, and preventing therebythe settling of shavings and the chokingof plane.

If desired, the cap may be provided with a series of grooves to lockwith two teeth or ridges of the iron, by which the exact connection ofcap and iron, without chance of changing their position on applying thelever, is retained.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of a plane-iron, having guide-slot,with the cappiece, adjusted and secured by an eccentric lever pivoted topost of the same, substantially as and for the purpose set forth.

WILLIAM YOUNG.
